WARNING: No mapping found for HTTP request with URI org.springframework.web.servlet.PageNotFound noHandlerFound

Question

I am learning Spring MVC and I am blocked since a few hours in this problem, that should have an obvious resolution:

• I am defining in web.xml the DispatcherServlet springSoccer and configuring it in springSoccer-servlet.xml under WEB-INF directory.

• In springSoccer-servlet.xml I am configuring the ViewResolver setting up the component scan pointing to the package of my controller.

I am deploying in Tomcat 8.0 and when I point my browser to http://localhost:8080/SoccerSpringMaven3/springSoccer/users/ I am getting the error:

Nov 19, 2015 9:07:50 PM org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/SoccerSpringMaven3/springSoccer/users] in DispatcherServlet with name 'springSoccer'

It's just a problem of not finding my RequestMapping. Find below the configuration:

web.xml

SoccerController.xml

package com.spring.soccer.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class SoccerController {

    @RequestMapping("/users")
    public String printSoccerHome(ModelMap model) {
        return "HelloSoccer";
    }
}

Any pointers?. Thanks a lot.

Answer 1

The <servlet-name> only defines which DispatcherServlet handles specific requests. It doesn't work like @RequestMapping annotation. You only configured Spring so that all requests are handled by springSoccer DispatcherServlet.

Read Spring MVC documentation- 21.2 The DispatcherServlet for more info.

In order for this request to work:

http://localhost:8080/SoccerSpringMaven3/springSoccer/users/

you have to either annotate your controller with @RequestMapping("/springSoccer") or annotate your method with @RequestMapping("/springSoccer/users")
